c++ - Puzzling Digital Mars C++ Behavior

Hello:
I discovered a behavior of the Digital Mars compiler that has me puzzled.
The small program reproduced below compiles without error as a .c program
but produces an error when compiled as a .cpp program, namely:
SC -cpp -r -Ae -Ar -Aa -mx -f -S -s -3 -a4 -c -oFPTR2.obj FPTR2.cpp
int (* t(int ix))(int *);
^
FPTR2.cpp(9) : Error: '(' expected following simple type name
The startling thing is that other compilers like DJ Delorie's DJGPP (ver 2.81),
Borland's BC++4.5 (bcc -ml -3 -k -N fptr2.cpp), and even (alas) Microsoft's
Visual C++ 4 compile this .cpp code without a complaint. I would be immensely
appreciative if you would clarify if this is some new C++ language behavior or
if this is some kind of bug.
Incidentally, replacing the declaration for the t-function with:
T t(int ix); //--FORWARD REFERENCE function prototype
where T is defined as: typedef int (*T)(int *k);
makes all the Digital Mars errors go away...
Thanks in advance for any assistance,
Stephen Zamoscianyk
